Posts from Where can I find the tool to generate an XXL map?
Which version of Heroes 3 are you referring to? SoD or WoG?
This is for WoG, or rather, a mod for ERA II.
XXL Mod
I downloaded the Erathia + Armageddon's Blade + The Shadow of Death collection, installed the HD patch, and that's it...
I don't have any additional expansions, like HotA or WoG.
Thank you in advance!

It contains a patched .exe file.
But! It's not possible to create a map using the existing HD mod (at least I couldn't), you can only play it, i.e.:
1. Place the rmg file in "Data"
2. Create a random map using the patched executable, choosing an XL map size (this will create an XXL-sized map)
3. Exit the game from the patched executable and play this map through the standard HD mod, finding it either in the save or in random_maps.
upd: but it’s better to use HotA for these purposes; those features are already built into the game and have been tested.
